摘要:
为了促进我国西南地区人口、资源与环境协调发展,基于已有的分析框架,对相对资源承载力模型进行扩展.在自然资源子系统中,纳入水资源、森林资源和水能资源3个指标;在社会资源子系统中,将人口质量因素纳入分析范畴.基于改进后的模型分析雅安市的相对资源承载力状况,结果表明:①在传统模型下雅安市人口处于超载状态,而改进的模型则显示相对资源承载能力仍存在一定的富余;②自然资源对资源综合承载力的贡献处于绝对优势,其他资源的贡献率显著偏低;③就雅安各区县而言,名山、汉源和芦山等县为超载状态,荥经为临界状态,其他各区县为富余状态.雅安市应在保护生态环境、促进人地关系和谐的前提下,增强经济、社会资源对人口的承载能力,减轻对自然资源的依赖.%To enhance the development of relationship among population,resources and environment in Southwest China,and based on the frame structure of analysing relative carrying capacity of resources,the paper makes two changes for relative carrying capacity of resources:① take the human capital as an indicator of social resources;② added the water,forest,and water power resources as three important indicators to the nature resource system.Then the paper analyzed the relative resources carrying capacity evolution process in Ya'an using the extended model.Results showed that:① overall it is in a surplus state which is in the opposite of the result from the traditional model of carrying capacity in Ya'an;② the natural resources make the most contribution to comprehensive carrying capacity of resources of Ya'an;③ among the comprehensive carrying capacity of the counties of Ya'an,Mingshan,Hanyuan and Lushan are in an overload state,Yingjing is in the state of saturation,and other counties are in the surplus state.Under the premise of protecting the natural environment and enhancing the harmonious friendship between human and nature,Ya'an should make more efforts to develop its economy to strengthen its relative carrying capacity of economic resources and relative carrying capacity of social resources,also reduce the degree of human relying on natural resource.
